DETAILED DESCRIPTION

Figures to be described show an embodiment of a bag according to the invention.

In the different figures, the same references denote identical or similar elements. In addition, the terms "lower," "upper", "high", "low", "forward", "back" etc .. are used in the drawings for greater ease of understanding. They should not be understood as limitations of the scope of the invention.

The luggage shown in FIG 1 is of the "trolley", and comprises a body 1 of luggage comprising two half-shells 2 and 3 of substantially rectangular section, connected together by a hinge 4 that runs substantially the entire height of the body 1 of the luggage on a luggage 5 side (or side face 5).

The half-shells 2 and 3 are rigid shells or semi-rigid, e.g. obtained at least in part by molding.

The half shells are assembled together by their free edges 7 by means of a slide fastener 6 running all along the free edges 7 of the two half-shells 2 and 3.

It will be understood by "free edge 7" the edge of each half-shell which is not connected to the hinge 4. Figure 3 illustrating a half-shell 3 shows only the free edge 7 of the half-shell 3.

The two half-shells 2 and 3 assembled form the six side faces of rolling luggage, two side faces 5, a front face 8, a rear face 9, a top face 10 and a bottom face 11.

The two side faces 5, the top face 10 and bottom face 11 are formed by two lateral edges of the half-shells assembled together by the hinge 4 or the zipper 6.

The front 8 and rear 9 also constitute side faces of the bag when the body 1 is positioned upright (see Figures 1 and 2 for example).

The side faces 5, 8 and 9 (comprising the front and rear), top and bottom are delimited by edges 12, 13 or 14 of the body 1.

The half-shell 2 comprises the four edges of the front face of the body 1 of the luggage. The edges 12 are rounded. In the examples illustrated by the figures, two reinforcement elements 15 are fixed to the upper corners of the half shell 2.

The half shell 3 forming the back of the body 1 has two side edges 13 in the hollow bag, the hollow forming a concavity, and the concavity facing the outside of the body of the luggage. The edge recess can also be referred to edge down edges.

It should be understood that the realization of a recessed ridge is not an essential feature of the invention and that it may extend to the following embodiments which the edges are flat, for example.

The half-shell 3 also has an upper edge 14 of bag body, separating the rear face 9 of the top face 10 of the body of the luggage. The upper edge 14 is also made hollow, whose concavity is facing outwardly of the body 1 of the luggage. The edge between the bottom face 11 of the rear face 9 is an edge 12 rounded, as the edges of the half-shell forming the front of the body 1 of the luggage.

The body 1 of the luggage is mounted on four sets of wheels 30 devices, each device having two wheels.

It should be understood that the roller devices could be different within the scope of the invention; for example, the devices could have only one wheel or more than two wheels.

Each device with casters 30 is attached and fixed to a corner of the underside 11 of the body 1 of the luggage.

Each of the roller devices is movably mounted about an axis

X1 which is parallel to the direction of the edges 12 or 13 of the body 1 of the luggage.

It should be understood that the invention is not limited to the presence of four devices on wheels: in fact, the baggage may contain only two devices on wheels, within the scope of the invention.

In the example illustrated, two of the four devices on wheels are associated with the two tubes 21 by being secured beneath the lower ends of the two tubes 21.

The lower ends 39 (Figure 4) of the tubes 31 comprise edges (not shown) which define a space within the tube.

Under the illustrated embodiment (see Figure 4), it is expected that the axes X1 of rotation of the devices 30 associated with roller tubes 21 extend into the internal space 21 to the respective tubes to which they are associated. More precisely, the pivot axis X1 and the X axis of the tubes are coincident.

Another embodiment (not shown) could also be provided, wherein each device on wheels is fixed to the vicinity of a tube to which it is associated, and each of the two swiveling axes is parallel to a main axis X of the tube which said roller device is associated, a pivot axis X1 of a device with casters being spaced from a main axis X of the tube associated therewith by a distance less than 20 millimeters.

In such a case, the swivel axis of the castor means is offset from the axis of the tubes.

Preferably, the distance between the axis X1 of rotation of a

device on wheels and the main axis X of the tube associated with it can be chosen zero.

It could also be provided, without departing from the scope of the invention, each of the roller devices is fixed to an element attached to a tube 21.

According to the invention, rolling luggage includes a dual telescopic rod 16, fixed to the body 1 of the luggage, and capable of assuming a plurality of positions between two extreme positions: a retracted position shown in Figures 1 and 6 to 8, and a deployed position shown in figures 2 to 5.

The dual telescopic rod 16 comprises two parallel arms 17, each formed from one or more rods assembled together.

The dual telescopic rod 16 also includes a handle 18, connecting the two free ends 19 of the two arms 17.

The handle can be fitted with a release button 20 of the double rod when it is in retracted position (or retracted) so as to permit a passage from the retracted position to the deployed position.

The two arms 17 of the double rod 16 are slidably mounted in two tubes 21, and the two tubes 21 are fixed along the edges 13 of the half shell 3 forming the rear of the body 1 of the bag outside of the half -Shell 3 and therefore of the body 1 of the luggage (see figures 4 and 5 in particular).

In this way, and as can be seen in particular in Figure 3, inside the shell 3 has a perfectly flat background and clutter of the tubes 21 receiving the arm 17 is minimum as well inside the luggage and outside, thanks to the fact that the tubes 21 are placed at the edges of the bag.

More specifically, the tubes are profiled with a section defined by an outer portion 22 and an inner portion 23 (see Figure 10).

The outer portion 22 defines an arc (or in other words a curve), the ends 24 and 25 tangentially joining the lateral faces 5 and rear 9 of the body 1 of the bag (the faces 5 and 9 are contiguous).

In this way, the outer portion 22 of the tube 21 appears to prolong the side face 5 and rear face 9. Thus, visually, the tubes 21 fit into the extension of the luggage faces and blend into the bulk of the bag, congestion luggage being laterally delimited by the faces 5, 9 and 8 of the baggage.

In this way, the tubes 21 do not clutter the interior of the bag. While the tubes 21 were placed inside the baggage, as is usual, they could damage the items contained in the baggage.

May be noted that the useful volume of the bag (that is to say the internal volume of baggage accommodating objects corresponds to at least 80% of the volume delimited by the outer surface of the luggage.

Moreover, the tubes 21 do not harm exterior aesthetics of the luggage.

Finally, they are not protruding outside the baggage, and so less fragile.

Generally, the outer surface (that is to say, visible) of the tubes 21 engaged in the recesses 13, form edges which are luggage shape and size substantially identical to the ridges 12. Thus, the body of the luggage is compact and has a regular outer form, symmetrical, giving the bag an elegant and aesthetic form expected by the consumer.

Furthermore, as shown in Figure 10, the inner portion 23 of the tubes 21 have a complementary shape to the recessed shape of the edges 13. The inner portion 23 is thus configured to substantially conform to the recessed shape of the edge 13 .

The tubes 21 are fixed in the recessed edges 13, for example by means of rivets or screws 26 (see Figure 3 showing the inside of the bag). The tubes 21 may also be fixed in the recessed edges 13 by other known fixing means, for example by gluing.

The fact that the tubes are brought outside the luggage by riveting or by screwing facilitates assembly of the luggage.

Furthermore, the cane tube attachment means do not undermine the integrity of the elements contained in the baggage. Indeed, they are few (two per tube) and placed substantially at the ends of the tubes and the edges of the bag.

It should be recalled that the walls forming the luggage faces are rigid or semi-rigid. Also, it is not necessary to provide two cross-connecting pipes that are typically found on the type of baggage "trolley".

Instead of such ties, the bag according to the invention has a rigid intermediate piece, fixed in the ridge upper hollow which allows to provide rigidity between the two tubes 21 in the upper part of the luggage (see Figures 8 and 9).

The rigid intermediate piece 27 is placed between the open ends 28 of the tubes (the open ends of the tubes 28 receiving the arms 17 of the double rod 16) so as to maintain the distance between these two ends. Indeed, without this piece, the wall forming the rear face of the body 1 of the bag may be deformed if the user was required to pull the bag by pulling on one side of the handle 18 or an arm 17, and handle may then get stuck in an intermediate position between the extended position and the retracted position, by a phenomenon of jamming or even deformation of the arms or tubes.

The intermediate piece 27 thus ensures rigidity of the top of the luggage.

The intermediate part 27 is illustrated in Figure 9: it is a rigid curved sheet whose shape is complementary to that of the upper recessed edge 14 of the body of the luggage. The length of the rigid curved sheet is substantially equal to the distance separating the two openings 28 of the tubes 21 of the luggage.

One can also provide other rigid curved sheets in the bottom of the recesses 13 recessed edges between the bottom edges and the hollow tubes 21.

Such rigid sheets are fine curves and mass scarcely heavier baggage: in any case, far less than the mass of the sleepers usually in the luggage such as "trolley".

The luggage remains so light and elegant.

The handle 18 is also shaped so that when the handle is in the retracted position (Figures 1 and 6 to 8), it fits in the space of the luggage delimited by the faces of the body of the luggage. The handle is thus not protruding and merges with an edge of the bag (or forms the edge of the bag), in the same manner as tubes 21 merge with the edges of the bag.

To do this, the handle has a section (shown in Figure 9) which has an outer portion 31 facing the outside of the bag when the handle is in the retracted position, and an inner portion 32 which faces towards the inside of luggage (and thus towards the upper recessed edge 14 and the rigid intermediate member 27) when the handle is in the retracted position.

The outer portion 31 defines an arc (or a curve) which has two ends 33 and 34. When the handle 18 is in the retracted position, the ends 33 and 34 form the arc portions whose extreme tangents are in the extension of planes defined by, respectively, the rear face 9 of the bag and the top face 10 of the luggage.

As for the inner portion 32, it is configured so that, when the handle 18 is in the retracted position (Figures 8 or 9), a free space 29 is present between the handle and the rigid intermediate piece 27.

This free space 29 allows sliding fingers under the handle to grasp and move it from the retracted position to the deployed position.

As can be seen in Figures 1 to 3, for example, the luggage also includes a second upper fixed handle 35, fixed on its upper face 10, in particular on the upper face portion formed by the shell 3. The baggage includes also a third side fixed handle 36, fixed to the side face 7 of the baggage, in particular on the side face portion formed by the shell 3.

The upper fixed handle 35 provides the user with a gripping member for moving the luggage manually without having to deploy the double rod 16.

The lateral fixed handle 36 provides the user a gripping element to enter the luggage manually by the lateral side of the luggage (e.g., up or down stairs).

The tubes 21 may be made of metal or any other lightweight and resistant Any material. In order not to damage or distort the tubes, there may be provided devices for cushioning adjacent tubes.

Figures 4, 5 and 7 show the damping elements 37, fixed on the rear face 9 of the bag parallel to the tubes 21 in the lower part of the rear surface 9.

The damping elements can be made of plastic or rubber.

Such elements could also be provided directly on the tubes 21. In yet an alternative embodiment, the tubes 21 themselves may be made of a suitable shock-absorbing material.

It is understood from the above description how the invention allows to have a stylish bag, compact, durable and functional.

Thus realized, luggage includes a dual probe 16 which is discrete as it is merges into the contour of the luggage. The probe 16 allows not only pull the luggage but also, thanks to its

provision it provides additional stiffness on three edges of the bag. Another advantage provided by the arrangement of the cane is that both tubes themselves can provide protection against shocks, such shocks that can damage the lower structure of the luggage when it is for example drawn to mount steps sidewalks or stairs.

It will however be understood that the invention is not specifically limited to the embodiment shown in the figures and that it extends to the implementation of equivalent.
